Our Step Up Capacitor Inverter

USING A 24 VDC INPUT

This type of inverter is unlike any you have ever seen before, Although capacitors are used widely in commercial inverters all over the world, We designed this system especially for the back yard researcher in mind, it is simple, low cost compared to buying a $3,000 commercial inverter. You may already have all the parts you need at home in your shop. this type of inverter will use 24 volts DC or you can add more capacitors to allow it to run on 12 volts DC. but for example we will show you the 24 volt DC method only. 24 volts DC is much more safer than using 120 volts DC. there is much less chance of a spark igniting the hydrogen gases and less chance of someone getting shocked to death!

If you do not now what a capacitor is then do not build this inverter yet. Go down to your local Radio Shack and buy a $4 beginners book on electronics called: GETTING STARTED IN ELECTRONICS, ( Page 32 ) This book will also teach you what an SCR is. Most of the parts can be purchased at Radio Shack or purchased by mail catalogs: call these 2 company's and ask them to send you a free catalog.

SO HOW DOES IT WORK?

First of all we start with 2 deep cycle marine batteries connected in series to get 24 volts dc. Now we must take that 24 vdc and step it up to 144 vdc, and we will do that by using our new method of using capacitors as batteries, put together in series, EXAMPLE: Charging and using 2 capacitors; ( see page 19 ) Charge #1 capacitor with 24 vdc and charge #2 capacitor with 24 vdc, Now remove the charge and each capacitor now has a full charge of 24 vdc. ( Each capacitor should be taped to your table for this experiment.) now using one alligator clip or wire, connect the + to the - as you would 2 batteries and you will now double the voltage from 24 vdc to 48 vdc. BE CAREFUL DO NOT TOUCH THE ENDS OF THE CAPACITORS. YOU MUST DISCHARGE ALL CAPACITORS WITH A WIRE BY SHORTING THEM OUT OR BY CONNECTING A LOAD SUCH AS A 100 WATT LIGHT BULB.

Please read this it is very important! YOU CAN NOT CHARGE EACH CAPACITOR WITH 24 VDC AND ALSO HAVE THEM CONNECTED IN SERIES ! You must do one or the other never at the same time! 1st you charge each capacitor, then 2nd you disconnect that charge, 3rd you then connect each capacitor ( that now has that powerful 24 volt charge ) and connect them in series. now it would be stupid to connect and disconnect all of this by hand. So what you must do is use switches! You can use all relay switches 1- 4 pole double throw and 5 - 30 amp auto relay switches, or you can use 1- 4 pole double throw relay and 5 - SCR's (Silicon-Controlled Rectifiers.) as switches. ( It is very easy to do!) Using SCR's is much quieter than using loud relays. you can buy low power SCR's at Radio Shack or you can buy High amperage SCR's by catalog. use 70 amp x 200v SCR's for a 1,000 watt unit, or 275 amp x 600 volt SCR's for a 5,000 watt unit. FIGURE #1 is the Charging diagram, this is where you will need to use the 4 pole double throw relay w/1-70 amp SCR on the positive lead, ( Radio Shack type cat. no. 275-214 12 vdc plug in relay. ) This relay is always in the up position, so the capacitors will be charging as soon as you connect the battery to the relay, then when you apply 12 vdc to the coil of the 4 PDT relay it will move the contacts down and this will turn off the charge. All of this will happen very quickly! Because instead of connecting the relay coil to the 12 vdc battery by hand you will be using our MOTOR MICRO SCR SWITCH METHOD The switching must be fast in order to charge the main capacitor bank, which you can apply your load to this, such as a 100 watt light bulb etc... DC only at this point. So you see what we are doing here is eliminating the need to place 10 - 12 vdc deep cycle batteries in series to get 120 vdc. we are simply using capacitors instead. But remember no matter what you do you will always need 10 deep cycle batteries for any average size home. NOTE: You could also build your own relay and use large bolt heads for contacts, and make your own 60 amp 4 PDT contact relay. But its not advisable, Using SCR's as switches work much better!

We Strongly Recommend that you Build a 100 watt inverter first using relays. Use 120 VDC to light a bulb!

This is the charging circuit, relay is in the up position and charging each capacitor. Be sure to use 115 vac extension cord wire, 8 amp or more. The more you stack these in parallel the more wattage you will get, and you will also need to use the proper wire size to handle the amperage coming through, If wire is getting almost hot or even warm replace

Do not apply load to #2 charge bank. Only To #3 bank!

TROUBLE SHOOTING: If you have a problem with the #2 capacitor bank shutting down . Then a back calapse has happeneO and you will neeO to recharge each capacitor again and then go to each one and discharge it with a Oischarging wire. ( SHORT THEM OUT ) if this Ooes not help try it again, if that still does not help you will have to take apart each capacitor from one another ana charge ana Oischarge again. The capacitors are still gooO. This should never happen once you have everything in place and fig #2
